5 The kernel's command-line parameters
14 The kernel parses parameters from the kernel command line up to "``--``";
18 Everything after "``--``" is passed as an argument to init.
32 This document may not be entirely up to date and comprehensive. The command
33 "modinfo -p ${modulename}" shows a current list of all parameters of a loadable
37 ``echo -n ${value} > /sys/module/${modulename}/parameters/${parm}``.
40 ----------------
44 	log_buf_len=1M print-fatal-signals=1
48 	log-buf-len=1M print_fatal_signals=1
50 Double-quotes can be used to protect spaces in values, e.g.::
64 	<cpu number>-<cpu number>
69 <cpu number>,...,<cpu number>-<cpu number>
75 	<cpu number>-<cpu number>:<used size>/<group size>
79 	isolcpus=1,2,10-20,100-2000:2/25
84 i.e "foo_cpus=16-N" would be equivalent to "16-31" on a 32 core system.
88 will also change.  Use the same on a small 4 core system, and "16-N" becomes
89 "16-3" and now the same boot input will be flagged as invalid (start > end).
91 The special case-tolerant group name "all" has a meaning of selecting all CPUs,
92 so that "nohz_full=all" is the equivalent of "nohz_full=0-N".
